Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\int \simplify{1/(x-{a})} dx \,$ = Unnamed gap

$+C$

Advice

Using the method of substitution with $u = \simplify{x-{a}}$ , we see that $du = dx$ and so

$\int \simplify{1/(x-{a})} \, dx = \int \frac{1}{u} \, du = \ln{u} + c = \ln{(\simplify{x-{a}})} + c.$ The answer is therefore

$\ln{(\simplify{x-{a}})}$

Give a worked solution to the whole question.
